Toi all .whom t may concern.'

Be it'known that L @Hannes Narr-IAN JoriNsoN, a. citizen oi the UnitedStatesoi` knock-down sectional character adapted for' ready assemblageof its parte5 and with any desired number of sections hung in verticalalinement, so as to acilitateready adjustment according tothe Weight ofthe sash to be balanced; and to provide a form of counterpoise structureand method of commercial distribution and fabrication Which Will-permitindependent `manufacture and shipping of, its several parts to the pointof retail or use, Where said parts may be put together by unskilledlabor ready for use inthe Window casing.

Anillustrative embodiment of this invention isf showinv in theaccompanying drawings, in Which,-

Fig. 8 showsan assortment of rodsadapted for two, three and fou-rfull-sized blocks respectively. i

inl thel construction Nshownin the` draw. ings the WindowT casing 1 isprovided with a lower sash 2 and an upper sashJ 3. A single sash -Weight4 is provided on each side of' the casing as Will be understood, eachof" said Weights being supported by a Window cord 5 runningonv a pair ofstationary sash pulleys 6 and 7 journaled in alinement in the upper partof the casing and corresponding with the sashes 2 and 3 respec tively.

The counterpoise 4 is provided Withl an equalizing pulley 8 whichreceives the cord 5 and thereby renders the Weight eifective forbalancing` both sashes.

In order that the counterpoise may be adjustable to accommodate Windowsashes of different sizes, the member 4 is made in sections 9 adapted`for Stringing together in series as on a rod 10. The Wheel of pulley 8is pivoted at 11 in a frame 12 which in turn is pinned at 13 to theupper end of the rod 10.y The rod itself is secured to a Weight 4 bymeans of a Cotter-pin or the like as shown all 14.'

Each Weightsection 9 is made in the form of arconcrete block ofrectangular shape and provided With.A a longitudinal axial perforation 9having a cross section corresponding with the shape of the rod 10whereby relative turning ofthe rod in the sectionsis prevented.

rlfhe rods 10 may bevmade up in various lengths adapted to supportyveightscomprising one, two, three or `more sections respectively, asmay be required in any instance, or therods may be made up long` enoughto accommodate a maximum number me sections and provided Withperforations 15 so located that the rod may be cut as at points 16 t0proper length to accommodate any desired number of sections and theholes being arranged to properly position the necessary retaining pin asillustratedy in Figs, 6l and 7.

The frame 12for pulley 8 is preferably made in the form of a sheetlmetal punching- 17, the, stamping for rwhich is of substantially theshape shown inFig. 4. In order to form this-punching into the shapeshown' in Fig. 2, connecting part 18 is bent into a til-shape as bybendingonthe lines 19, and the,V T-ends 2O are bent inwardly at theirtirsv 21,@5 by bending 011 the lines 25ay In punching this member holesare provided at 23 to receive the pulley pintle 11 and at 24 to receivethe rod pintle 13. A rectangular hole 25 is also punched in the middleof part 18 to receive the upper end of rod 10,

The blocksV 9 are formed of concrete composed of a dense mineral matter,preferably slag, which has been ground and mixed with a suitable binderand water. This matter is molded into blocks by means of presses asunderstood in the art. In molding the blocks the central perforation isprovided by means of a core which is withdrawn when the block is removedfrom the meld, the details of which process need not be here explainedas the method is well understood by those skilled in the molding art.The special advantages of using slag are its density and its abundanceand cheap cost. In fact, the cost of slag may be regarded as negligibleas it is regarded generally as a waste product having no establishedutility whatever. Y

The method of manufacturing, merchandizing and using the device hereinshown and described lis as follows Ihe blocks may be molded in thevicinity of a steel mill or other source of slag. The sheet metal frames12 may be manufactured at a factory specializing in sheet metalpunchings. The pulleys are preferably formed by spotwelding twopress-formed sheet metal punchings together as at 8, or cast pulleys mayVbe used. The pulleys may bemade wherever convenient, and the cordswill, of course, come from some other source. The several parts ifdesired may be finished and stored in the vicinity of the point ofmanufacture and may then be shipped directly to the point of ultimateconsumption or use whenever required for filling orders and for thispurpose may be shipped directly to the building where they are to beused. The parts may then be assembled and the in ished productmay befabricated at the immediate pointV of installation by unskilled hands. Agreat advantage of this method ofshipping the parts separately andVassembling at the point of installation is that the several parts maybe shipped in bulk according to their own respective freight rates, thatis to say, the weights or blocks may be shipped as bricks, andthe otherparts according to: their own characters respectively. `The expense Vofshipping" the goods is thus much less than would be required if'thedevice were assembled before shipment, in whichv case a high freightrate would apply, owing to the classification then being for amanufact'uredproduct rather thanfor mere materials. VAnother point ofadvantage in molding the bricks separately and providing interchangeablerods 1() and frames 12 is that rusting of metal parts is avoided for ifsaid parts were molded into or joined to the bricks when the latter weremolded, the metal would be subjected to moisture for a considerableperiod with the result that rusting would occur and a correspondingdeterioration in quality and appearance. As it is absolutely necessarylfor the curing or hardening process to keep the concrete weights wetfrom two to seven days, either by the use of steam or water,

the advantage of the concrete weight beingV separate from the pulleydevice during this period can be readily seen. The bricks are preferablysteam cured for 35 to 48 hours, and then yarded till needed to fillorders. It is to be understood that the bricks may be molded in variouslengths, and that a standard full sized weight unit measuring 2 x il x 8and` weighing about eight pounds may be supplemented with one or moretwo pound quarter size units each measuring 2 x 4l x 2. This assuresgreat flexibility and convenience,'as well as low cost. Special needsmay be instantly met by supplying the appropriate parts and fabricatingthe attachment accordingly, no tools being necessary excepting to bendthe pulley frame punching 17 into shape, and the parts all being`secured by the cotter pins 11, '13 and 14C. n

In making these weights I prefer touse one part of Portland cement withfour or five parts of slag crushed to pass through a screen of mesh,mixed with suiiicient water (10 to 15%) to make a good working concreteadapted for ready molding. I prefer to mix with this concrete about onethird part by weight of coarse slag ranging upward to about to in size.The aggre-` gate contains slag particles ranging in size all the waydown to small grains or dust. l In the manufacturing of concreteweights,

using a power brick machine, (with perfo-v rating device), seven men canproduce 10,000 weights per day, 9 hours labor. Anv

important advantage in the use of a lpower machine, is that 40 tonspressure may be developed insuring a denser brick compared with weightsproduced in the ordinary ways. They are true and uniform, and the coreaperture is adapted to receive a flatstringing-rod in non-turningrelation. Moreover,

this method produces a weight of uniform density, and a weight which issmooth and can be handled with a minimum chance of breakage. Y

The pulley frames or casings 12 may be stored and shipped at and thenbent into shape aftershipment, at the point-of use.

In shipping, the concrete blocks pass as common brick, the pulleyattachments as sash pulleys, and the other materials `ac` cordingly, 'sothat minimum' rates apply. Packing expense is vreduced to a minimum andis largely eliminated. f y

Although but one complete specie embodiment of this invention is hereinshown and described it is to be understood that some of the details ofthe construction shown may be altered or omitted Without departing fromthe spirit of this invention as defined by the following claims.

I claim:

l. A sash Weight comprising a dense concrete block having an axialperforation, a supporting member extending through said perforation,cotter pin means for securing` said member in said perforation, a pulleysecured to said member, and means adapted for detachabbT connecting saidpulley to said member.

2. A sash Weight hanger comprising a pulley Wheel, a sheet-metal framewherein said Wheel is mounted and a rod having one end detachablysecured to the lower part of said frame.
